The hepatic nematode is a zoonotic parasite primarily parasitising small mammals, but it can infect a wide range of mammal species, including humans. Due to its specific life cycle and transmission pattern, it is one of the least studied helminths in the world. The only documented findings of from Slovakia (former Czechoslovakia) come from the 60s and 70s of the 20th Century, including nine human cases of the infection reported .

Bacteriocins (enterocins) represent a new therapeutic strategy in various intestinal and non-intestinal infections. In antiparasitic defence, an oxidative inflammation of phagocytes is effective in destroying new-born larvae. The strains CCM8558 and ED26E/7 and their enterocins, enterocin M and a durancin-like enterocin, respectively, were administered daily, and mice were then infected with larvae on the seventh day of treatment.

Tatra chamois ( (Blahout 1972)) and Tatra marmot ( (Kratochvíl 1961)) are significant endemic subspecies of the subalpine and alpine ranges of the Tatra Mountains in Central Europe. In four studied localities in the range of their typical biotopes in Slovakia and Poland, we investigated intestinal parasites of Tatra chamois and Tatra marmots, with an emphasis on anoplocephalid tapeworms. We also studied the occurrence, species diversity, and abundance of oribatid mites as intermediate hosts thereof, and the prevalence of cysticercoid larval stages of anoplocephalid tapeworms in collected oribatids using morphological and molecular methods.

The known data resulting from individual surveys of canine dirofilariosis point to the great differences in the epidemiological situation among countries where Dirofilaria parasites emerged approximately at the same time. In this regard, the Czech Republic and Slovakia, neighboring countries situated in Central Europe, could serve as an illustrative example of such a situation. The present study aimed to assess the prevalence of canine dirofilariosis in both countries and to discuss the reasons for potential differences shown.

The sialylation of the glycoproteins in skeletal muscle tissue is not well investigated, even though the essential role of the sialic acids for the proper muscular function has been proven by many researchers. The invasion of the parasitic nematode in the muscles with subsequent formation of Nurse cell-parasite complex initiates increased accumulation of sialylated glycoproteins within the affected area of the muscle fiber. The aim of this study is to describe some details of the α-2,6-sialylation in invaded muscle cells.

Although the grey wolf was on the brink of extinction in Central Europe in the last century, it never became extinct in Slovakia and nowadays its population is considered stable. The wolf population in Slovakia is estimated to be around 400 individuals with seasonal variations, and due to these small numbers, studies on the parasite fauna of wolf are scarce. Of the 35 parasitic species recorded worldwide in grey wolves in temperate and mountain zones of the Palearctic region, 15 were detected in Slovakia.
